The research aims to achieve the first total synthesis of cristatic acid 1, a secondary metabolite with significant biological properties, including antibiotic activity against Gram-positive bacteria, hemolytic properties, and cytotoxicity. The synthesis is challenging due to the presence of a labile furan moiety, which restricts reaction conditions. The researchers successfully synthesized cristatic acid by employing palladium-catalyzed alkylation of vinylepoxide 10, derived from sulfonium salt 8, and using SEM ethers as protecting groups for phenolic OH functions. Key chemicals used in the process include methyl orsellinate, prenyl bromide, SEMCl, SeO2, tertBuOOH, mesyl chloride, LiBr, Pd(PPh3)4, dppe, and various other reagents for deprotection and functional group transformations. The successful synthesis of cristatic acid not only demonstrates a feasible route to this bioactive compound but also paves the way for further studies on the biological response to changes in functionality. The conclusions of the research confirm the structural integrity of the synthesized cristatic acid through X-ray analysis and other analytical and spectroscopic data, which are in full agreement with literature reports.
